Looks fine to me.  I can see variation in the black.

I use the following test pattern that I save to the HD: http://www.photofriday.com/calibrate.php

I use Powerstrip to get the changes to stick because my monitor controls only go so far (Acer): http://entechtaiwan.com/util/ps.shtm

Powerstrip can also adjust the temperature if your monitor is off a bit there too.  It can do much more than that too.  It is around $30 and worth every penny.  Running Windows 8 here.
